The 6G Debate Europe Needs to Have Before It Has the Technology

Next week in Brussels, a room full of telecom executives, regulators, and policy researchers will gather to discuss something that doesn't exist yet. The CEPS workshop on 6G and edge AI, scheduled for 29 September, promises to address "market and regulatory evolution" toward a technology whose standards haven't been finalized and whose commercial deployment remains years away.

This might sound premature. It isn't.

The question worth asking: is Europe preparing for 6G as a genuine industrial opportunity, or is it setting up the regulatory furniture for a party that will happen elsewhere?

Three Layers of a Single Problem

The CEPS event structures itself around three panels, each addressing what appears to be a distinct question. The first examines industrial strategy. The second focuses on the Digital Networks Act (DNA), the proposed regulatory framework for European connectivity. The third looks at competition policy, merger control, and the economics of network investment.

But these aren't really three separate conversations. They're three angles on the same underlying tension: Europe wants technological sovereignty in next-generation networks while operating within a market structure that may not support the capital expenditure required to achieve it.

The European Commission's 6G policy page frames the stakes clearly: 6G will bring "pervasive and seamless connectivity" integrating AI, sensing, and communication. Applications range from remote surgery to autonomous vehicles to digital twins of physical infrastructure. The Commission established the Smart Networks and Services Joint Undertaking (SNS JU) with a €900 million EU budget between 2021 and 2027, to be matched by industry.

Is €1.8 billion over six years enough? That depends on what "enough" means.

The Scale Problem Nobody Wants to Quantify

Market projections estimate the global 6G market will reach approximately $57.55 billion by 2035, growing at a compound annual rate of 23.45% from 2026. North America currently holds roughly 39% of market share, with Asia Pacific identified as the fastest-growing region.

Notice what's missing from that breakdown: Europe's projected share.

The numbers reveal a structural challenge. 6G isn't just faster 5G. It represents a convergence of connectivity, distributed computing, and AI deployment at the network edge. Technical research describes 6G as "native-AI" infrastructure, where intelligence becomes a built-in network capability rather than an application running on top of it. This means the investment required isn't just in spectrum and towers. It's in computing infrastructure, AI capabilities, and the integration layer that connects them.

A Bruegel analysis from 2024 put the EU's position bluntly: the cost of catching up with leading big tech AI computing centers "is already prohibitive for EU budgets, and is set to become even more so." The EU attracted only 6% of global AI startup investment in the first half of 2024. The hardware focus, Bruegel argued, "overlooks missing EU markets for complementary services": large-scale business outlets, hyperscale cloud infrastructure, and private equity financing.

The 6G question and the AI question are the same question. Edge AI requires network infrastructure. Network infrastructure increasingly requires AI. Europe's position in one determines its position in the other.

What the Digital Networks Act Can and Cannot Do

The second panel at the CEPS workshop addresses whether the DNA can create "more coherent and investment-friendly conditions" for 6G deployment. The framing acknowledges Europe's "long-standing fragmentation problem": 27 national markets, 27 regulatory approaches, 27 sets of spectrum allocation decisions.

The DNA aims to harmonize. But harmonization addresses coordination failures, not capital constraints. A unified regulatory framework makes cross-border deployment easier. It doesn't make the underlying investment more attractive if the returns don't justify the expenditure.

The central question, as CEPS frames it: can the DNA create "credible incentives for the levels of long-term capital expenditure required for 6G deployment"?

This is a facts-and-incentives disagreement, not a values disagreement. Everyone agrees Europe should have competitive 6G infrastructure. The debate is whether the proposed mechanisms will actually produce that outcome.

The Competition Policy Dimension

The third panel broadens the lens to merger control, co-investment arrangements, and industrial cooperation. The underlying tension: telecom operators argue they need consolidation to achieve scale. Competition authorities worry consolidation reduces competitive pressure and raises prices.

Both positions contain truth. The question is which failure mode is more costly.

European telecom markets remain fragmented compared to the US and China. Operators argue this fragmentation prevents the scale necessary for major infrastructure investment. Regulators counter that consolidation without competitive pressure produces underinvestment anyway, just with higher margins.

The CEPS workshop description notes that "even an ambitious telecom framework won't be sufficient if broader competition and market-structure rules don't support the economics of next-generation networks." This is the crux. Regulatory coherence in telecom-specific rules matters less if the broader industrial and competition framework works against the stated goals.

The Vendor Ecosystem Question

Buried in the workshop description is a reference to "trusted supply chains, cybersecurity considerations, and standardisation and IP strategies." This is diplomatic language for a geopolitical question: which vendors will build Europe's 6G infrastructure?

The 5G debates over Huawei equipment established that network infrastructure is now a security concern, not just an economic one. 6G, with its deeper integration of AI and sensing capabilities, intensifies these considerations. The question of who builds the infrastructure is inseparable from questions about data flows, algorithmic control, and strategic dependency.

Europe's position here involves a three-way trade-off: cost (non-European vendors may be cheaper), security (some vendors raise concerns about data access and system integrity), and industrial policy (European vendors need market share to remain viable). Optimizing for any one of these dimensions creates costs in the others.

What Would Have to Be True

For Europe to achieve genuine 6G competitiveness, several conditions would need to hold simultaneously:

• The DNA would need to reduce fragmentation enough to make pan-European deployment economically attractive.
• Competition policy would need to permit sufficient consolidation for scale while maintaining enough competitive pressure for continued investment.
• Industrial policy initiatives like CAIDA and the Apply AI strategy would need to deliver actual capabilities, not just funding announcements.
• The broader AI ecosystem would need to develop the edge computing and distributed intelligence capabilities that 6G infrastructure requires.

Each of these is uncertain. All of them together is a significant bet.

The alternative framing, suggested by the Bruegel analysis, is that Europe should focus on "productivity growth below the AI technology frontier" rather than trying to match frontier capabilities. Applied to 6G, this would mean accepting that Europe may not lead in core infrastructure while focusing on applications, services, and specialized use cases where European strengths apply.

This is a legitimate strategic choice. But it's a choice that should be made explicitly, not arrived at by default through underinvestment.

The Debate Worth Having

The CEPS workshop on 29 September won't resolve these tensions. But it might clarify them. The value of structured policy debate isn't reaching consensus. It's making the actual disagreements legible.

Is Europe's 6G challenge primarily regulatory (fragmentation), financial (capital constraints), industrial (vendor ecosystem), or strategic (geopolitical positioning)? The answer is probably "all of the above," but the relative weights matter for policy design.

The conversation Brussels needs isn't about whether 6G matters. It's about what Europe is actually willing to do, and what trade-offs it's prepared to accept, to have a meaningful position in it.
